Experiencing a crash issue, dumped some info below, let me know if there's anything else I can provide too assist in debugging.

Yeah, please install the dbgsym package and do the backtrace again. Also please post the version/commit.

denislemire commented 6 years ago

Version is mr6.1.1.1 / 0b72381 - packages were built using dpkg-buildpackage but no dbgsym package was generated. Is there a build step I missed to generate the dbgsym package?

rfuchs commented 6 years ago

See issue #459 about the dbgsym package

denislemire commented 6 years ago

Building on 16.04 with DH_BUILD_DDEBS=1 with does get me dbgsym package.

Not sure the symbols would perfectly match the version I built previously though. Might be best for me to upgrade to the 6.2 branch (with debugging symbols installed) and see if the issue recurs there.

rfuchs commented 6 years ago

Yeah the dbgsym package would have to be from the same build as the one that dumped core.

denislemire commented 6 years ago

Based on that, not sure we can do anything more. I can submit an new issue if I experience a similar crash on the newer version. Next time around I'll have proper debugging symbols to generate a useful backtrace.

Thanks for the efforts, regardless!

rfuchs commented 6 years ago

Alright, submit a new issue if it happens again.
